Thanks Remah. I had read through the “Officail Single-Sign-On” thread and it helped me understand the Discourse side of it to some degree. But I couldn’t see that it said which SSO protocol I should be using on the Joomla side.
Thanks for the stackoverflow link. That helps fill in some gaps for me.
I was hoping someone here has already done what I need and might be able to explain in a few sentences the best way to accomplish this integration on both sides.
